Connecting the Robot and Controller
Brooks Automation provides an RS-232C connection for host control. The system host
transmits ASCII commands to the controller through a DB25 male connector. The RS-
232 serial port is located on the CPU card at the back of the controller box.
The RS-232 cable provides these connections: RX/TX, RTS/CTS, Signal GND, and
Shield. The shield is either soldered to the D shell connectors at each end, or con-
nected to the chassis of the host and controller by pigtail leads. The controller also
provides eight optically isolated inputs and outputs as well as Motor Off, Stop, and
Reset inputs through a DB37 female connector.
The baud rate (bits per second)is 9600.
The two signal cables connecting the robot and the controller are isolated from the
power cable. A three-prong, 100/120/220/240 V
AC
, 50/60 Hz cable is provided. The
current draw is 5 amps at 100 or 120 V
AC
, and 2.5 amps at 220 or 240 V
AC
.
See Vacuum Specifications on page 1-15 for vacuum requirements.
